Microcontrollers FAQ

Does the PIC18F65J50 support both low-speed and full-speed USB modes?

Yes, the integrated USB module supports both Low Speed (1.5 Mb/s) and Full Speed (12 Mb/s) communication as per USB Specification Revision 2.0.

What is the function of the Fail-Safe Clock Monitor?

The Fail-Safe Clock Monitor constantly monitors the main clock source against the internal oscillator reference. If a clock failure occurs, it switches the controller to the internal oscillator for continued operation or safe shutdown.
